UPDATE
The latest version of the Piano Groove Tutor, Version 0.7 is out now.
The major new changes are lockable volume and tempo settings and capability to create your own sessions. To download and read more about it go to the Piano Groove Tutor v0.7 page.
Version 0.5 discussed on this page has become obsolete and will no longer be downloadable. The sessions have also become obsolete because the version 0.7 sessions use a slightly different format. If you previously downloaded the v 0.5 sessions they should still work in version 0.7 (though I made a few minor changes to some of them). Playing the new sessions in version 0.5 also works but with a few hick-ups, such as the metronome tracks not playing and some instruments not being on the right channel.
I dedicated a separate page to the sessions (in their new format). That's were all the newly published sessions will appear from now on. You can view the Piano Groove Tutor Sessions here.
The information relevant to this version only, as well as the forum entries will still be available here. All the chapters also relevant to v 0.7 have now moved to the Piano Groove Tutor v0.7 page.
